Answer:
- 615.8 square feet
- 9 truckloads
Step-by-step explanation:
The area of the circular ring is given by the formula ...
A = πr²
where r is the radius, or half the diameter.
A = π(14 ft)² = 196π ft² ≈ 615.752 ft²
The area of the training area is about 615.8 square feet.
__
The number of truckloads of dirt required for coverage will be ...
(615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads
Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.
It takes you 4.8 hours to reach New York
Step-by-step explanation:
The given is:
- It is 240 miles from Boston to New York
- You drive at a speed of 50 mph
We need to find how long would it take you to reach New York
Distance (d) = speed (v) × time (t)
∵ The distance between Boston and New York is 240 miles
∴ d = 240
∵ You drive at a speed 50 miles per hour
∴ v = 50
- Substitute these values in the rule of the distance above
∴ 240 = 50 × t
- Divide both sides by 50
∴ 4.8 = t
∴ The lime of the trip is 4.8 hours
It takes you 4.8 hours to reach New York

Step-by-step explanation:
1. y = 4x + 9 ; m = 4 ; b = 9
the slope is 4 because there’s a pattern of +4 going down the function table in the “y” column
and b= 9 because at the number 0 on the x line has 9 in the y box
2. y = 3x - 1 ; m = 3 ; b = -1
basically the same thing as the first one just different numbers
Answer:
m = (n/3) - k
Step-by-step explanation:
n = 3(k + m)
n = 3k + 3m
n - 3k = 3m
3m/3 = (n - 3k)/3
m = (n/3) - k
